WATER-CLOSET AND TANK.

' Specification of Letters Patent. Patented Nov. 30, 1909.

- Application filed October 21, 1908. Serial No. 458,802.

To all whom it may concern:

Be it known that I, JOSEPH W. SHARP, Jr., a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful Improvements inWater- Closets and Tanks, of which the following is a specification.

The present invention relates to water closets, and particularly toclosets of the low-down tank type.

It has for one of its'objects to provide a construction in which themetal fittings and connections between bowl and tank are entirely orsubstantially concealed.

Another object is to provide closet and tank connections which may bequickly and conveniently made, without the necessity of setting up nutsand couplings, and which will at the same time effectually seal thejunction between the parts.

A still further object is to provide for drainage of any water ofcondensation from the tank to the closet bowl, and prevent floordrippings, tanks of metal or pottery being apt to sweat and drip undercertain atmospheric conditions.

In order that the invention may be clear to those skilled in the art Ihave illustrated in the accom anying drawings one embodiment thereo andin said drawings: Figure 1 isa side view of a closet embodying myinvention, parts of the construction be ing in section for clearness.Fig. 2 is a front view of a tank with a portion of the closet and theconnections in section. Fig. 3 is a plan view to show the lay out of theparts and connections. Figs. 4, 5 and 6, are, respectively, front, side,and top views of a pottery or metal tank to show the drainage featurefor condensation and drip. Fi 7 is a slightly different form of tank andbowl connection from that shown in Fig. 2, although embodying the samegeneric features.

Referring to the drawing by numerals, like numbers indicating like partsin the several views, 2 designates a closet bowl, which, so far as itsmain features are concerned may be of any suitable or desired type. Thesaid bowl 2 is provided at its rear with an upstanding portion 3,through which pass such bowl-flushing and ventilating passages as may beused, as, for example, passages 4 and 5. Surrounding at least one thevalve 10 which present instance, is a groove or seat 6 of considerabledepth, said seat 6 being designed to receivethe downardly projectingflange 7 on a valve nut 8 which engages the end 9 of projects downwardlythrough the bottom of the tank 11, the usual packing rin s 12 beinginterposed between the nut 8 an tank bottom and the valve bottom andtank floor. Similarly the vent pi e 13, whereone is used, is secured inplace by nut 14, as clearly shown in Fig. 2.

The tank 11, shown in Figs. 1 and 2, is of the ordinary ty e, and asWlll be clear, rests upon the raised portion 3 of the bowl, the usualwall fastenings (not shown being provided at rear of the tank 11.

en the ,tank 11 is placed on the raised portion 3 of the bowl, the lowerends of the valved supply pipe and the vent pipe, enter the passages 4and 5, the flan e 7 on the nut 8 entering the seat 6 surroun ing thepassage 4, so that the tank 11 forms a flush joint with the raisedportion 3 of the bowl, and all fittin s and connections are inclosed andconceale The seat 6 for the nut flange 7 will, in practice, he filledwith cementitious or sea1- ing compound 15 in which the flange willembed itself and an absolutely will thus besecured.

The top of the raised portion 3 of the bowl has a depression or sink 16formed therein, from which provision is made for drainage, such as adrainage groove or hole 17 leading to a sloping or curved wall 18 at theback of the bowl 2, so as to drain the contents of the sink 16 directlyto the bowl, although obviously any suitable drain arrangement otherthan that shown might be adapted. This drainage feature is designed foruse with tanks of metal or pottery, such as shown in Figs. 3, 4 and 5,the tank 19 being sloped downward to its bottom, so that the area of thebottom is slightly-less than the area of the sink 16. The result of thisconstruction is that when the tank 19 is in position on the raisedportion 3, all dri pings from sweating of the tank will be dirccted tothe sink 16, and drain to the bowl through the hole 17 and incline 18.thus preventing floor drippings.

In respect of fittings and junction the tank 19 and raised portion 3 aresimilar to the arrangement above described in connection with Figs. 1, 2and 3.

tight joint- In Fig. 7 the tank and bowl connection is shown asembodying a flanged nut 20 similar to that shown in the other views, butinstead of dro ping into a depression the tank seat, the dependingflangeof this nut drops into a cup-shaped nut 21, secured to a s ad 22 fixedlymounted on the tank seat. The cup-shaped nut 21 is supplied with acementitious filling into'which the de ending flan e of the nut 20 sinksto form t e seal, the ange 23 ofthe nut resting upon and being supportedby the flange of the cup-shaped nut 21, which, in turn, rests on thetank seat. This construction takes all strain ofi the joint between thetank and bowl, and furthermore provides a joint which may be separatedwithout the necessity of unscrewing the connecting parts.

It will be seen that in both .the form shown in Figs. 1 and 2, and thatshown in Fig. 7, the weight of the tank tends alwa s to force the flangeof nut 20 down into t e sealing com ound and make a tight joint. When itis desired to separate the tank and bowl, this joint may be broken outwithout disturbing any of the fittings, and if, as

preferred, a cementitious substance sensitive to heat isused, the jointmay be loosened by heating the metal parts, including nut 20, in anysuitable manner, as by the application of hot water, and the partsreadily separated. It is obvious that some latitude of struc-" ture fromthat disclosed may be indulged in without departing from the spirit ofmy invention.

Having fully disclosed my invention, I claim:

1. The combination with a closet bowl, of a raised tank support at therear thereof of extended area to receive a tank, aitank resting on saidsupport, and concealed tank and bowl fittings and connections betweenthe parts.

2. The combination with a closet bowl having a tank seat at its' rear ofextended area to receive a tank and provided with passages, of a tankhaving a flush fit on said seat, and tank and bowl fittings andconnections concealed between the parts.
